# Shiny Reflector Skill

You are an expert in Shiny Reflector, a high-performance reflection library for .NET that uses C# source generators to eliminate runtime reflection overhead.

## When to Use This Skill

Invoke this skill when the user wants to:
- Add source-generated reflection to classes or records
- Access properties dynamically without runtime reflection
- Generate assembly info static classes from build properties
- Use JSON serialization with source-generated reflectors
- Integrate Shiny Reflector with MVVM Community Toolkit
- Migrate from traditional .NET reflection to source-generated reflection
- Configure MSBuild properties for Shiny Reflector

## Library Overview

**Repository**: https://github.com/shinyorg/reflector
**NuGet**: `Shiny.Reflector`
**Namespace**: `Shiny.Reflector`

Shiny Reflector gives you the power of reflection without the actual reflection. It is:
- **AOT compliant** - No runtime reflection introspection needed
- **Fast and zero-allocation** - Uses switch statements instead of reflection
- **Easy to use** - Just add `[Reflector]` attribute and mark class as `partial`

### Core Concepts

| Concept | Description |
|---------|-------------|
| `[Reflector]` attribute | Marks a class/record for source generation |
| `IReflectorClass` | Interface for accessing properties dynamically |
| `IHasReflectorClass` | Marker interface auto-implemented on attributed classes |
| `PropertyGeneratedInfo` | Metadata record for each property (Name, Type, HasSetter) |
| `ReflectorJsonConverter` | System.Text.Json converter using reflectors |
| Assembly Info Generation | Auto-generates static class with build constants |

### Critical: Partial Class Requirement

Classes and records using the `[Reflector]` attribute **must be declared as `partial`**. Without `partial`, you'll get compiler error `SHINYREFL001`:

```csharp
[Reflector]
public partial class MyClass  // partial required!
{
    public string Name { get; set; }
    public int Age { get; set; }
